Using the tsconfig option

[nickpitrak]

Hi there! I'm having some trouble using the tsconfig option for configuring Jest with ts-jest 26.4.4. According to the options page (https://kulshekhar.github.io/ts-jest/docs/options/), my jest.config.js should look something like this:

module.exports = {
    globalSetup: '<rootDir>/test/setup.js',
    preset: 'ts-jest',
    testEnvironment: 'node',
    testRegex: 'test/*/.*\\.test\\.ts$',
    globals: {
        'ts-jest': {
            tsconfig: 'tsconfig.dev.json'
        }
    }
}

I've also tried including the tag in the globals:

module.exports = {
    globalSetup: '<rootDir>/test/setup.js',
    preset: 'ts-jest',
    testEnvironment: 'node',
    testRegex: 'test/*/.*\\.test\\.ts$',
    globals: {
        'ts-jest': {
            tsconfig: '<rootDir>/tsconfig.dev.json'
        }
    }
}

With my tsconfig.dev.json set to not report noUnusedLocals, I still see that error stop testing.

Also, the link on the option page linked above to see more about the tsconfig option gives me a 404 (https://kulshekhar.github.io/ts-jest/docs/options/options/tsconfig).

Can anybody help me try to figure out what else I should try?

The correct doc link is https://kulshekhar.github.io/ts-jest/docs/options/tsconfig

Maybe you can clear Jest cache after setting tsconfig ?

Thanks for the link!

Looking at this more, I made a mistake on my end. My test script was loading a different Jest config than I was expecting. Using the correct one, everything works. Sorry about that, but I really appreciate your help.
